Site Performance Measurement

Question

I need a website performance evaluation tool that is free and does not require any code changes (jsp asp pages). All help is appreciated.

Answer 1

To measure performance, I recommend YSlow , this Firefox add-on that integrates with Firebug , it analyzes your web pages and tells you why they are slow based on the rules for high performance websites .

Also, with the Firebug Network Monitoring tab, you can see which resources take more time and download bandwidth:

Answer 2

You can also use Fiddler , which will work for browsers other than Firefox. (But there will be no javascript code profile)

Answer 3

Other answers to this question relate to the performance of a single user of the site in terms of the browser. If you want to check the performance of your server, for example, to find out how many concurrent users you can support, you need to look for tools like JMeter .
